The release films 103 are used to protect the adhesive layer until use, preventing it from being contaminated by dust, dirt, etc. During use, simply peel off the release films 103 to attach the patch to the skin.

[0030] A waterproof and breathable membrane 101 is fixedly connected to a waterproof strip 13 on its inner side. A limiting block 14 is fixedly connected to the side wall of the waterproof strip 13. A guide groove 15 is provided between the waterproof strip 13 and the waterproof and breathable membrane 101. A water-absorbing tube core 16 is fixedly connected to the inner wall of the limiting block 14. The water-absorbing tube core 16 is located inside the guide groove 15. The water-absorbing tube core 16 is made of water-absorbing resin, which is a functional polymer material with a large number of hydrophilic groups that can absorb a large amount of water.

[0031] The covering component 2 is located inside the waterproof tape 13. The waterproof tape 13 ensures that water can effectively prevent water from seeping into the covering component 2 area even under prolonged use or contact with large amounts of water. The covering component 2 includes a reinforcing and stabilizing layer 201 fixedly connected to the inner side of the waterproof and breathable membrane 101. The main function of the reinforcing and stabilizing layer 201 is to increase the overall structural strength of the dressing, ensuring that it will not easily deform or break during use, thereby better protecting the wound. A polyurethane film layer 202 is fixedly connected to the side of the reinforcing and stabilizing layer 201 away from the waterproof and breathable membrane 101. The polyurethane film layer 202 is located away from the reinforcing and stabilizing layer 201. An antibacterial layer 203 is fixedly connected to one side of the 1. The antibacterial layer 203 contains antibacterial components and can effectively inhibit bacterial growth. A sweat-absorbing layer 204 is fixedly connected to the side of the antibacterial layer 203 away from the polyurethane film layer 202.

The medicine material layer 302 is the core part of the dressing component 3 and contains specific drug components. A dressing gauze 303 is fixedly connected to the side of the medicine material layer 302 away from the cotton wool layer 301. The dressing gauze 303 directly contacts the wound surface and plays the role of covering and protecting the wound. It is usually made of soft and breathable materials to ensure that the wound area can breathe and prevent external bacteria from entering. The dressing gauze 303 can also help to evenly distribute the medicine, making it better applied to the entire skin surface.

[0033] In summary, the working principle of a waterproof and breathable sterile dressing according to this utility model embodiment is as follows: When using, remove the dressing from the sealed package, ensuring hands are clean and dry. Peel off the two release films 103 on the dressing. These protective films prevent contamination of the adhesive layer 102 and adhesive layer 205 before use. Carefully apply the dressing to the body, ensuring adhesive layer 102 and adhesive layer 205 adhere tightly to the skin. With adhesive layer 205 and adhesive layer 102 adhered to the skin, the sweat-absorbing layer 204 absorbs sweat and other secretions, keeping the wound area dry and clean, and preventing skin irritation or infection caused by moisture. The medicated layer 302 acts directly on the wound surface through the medicated gauze 303, providing continuous drug release and promoting wound healing. When it is necessary to change or adjust the position of the dressing, pull the tear strip 11. The tear strip 11 causes a corner of the waterproof and breathable membrane 101 to tear, making the dressing easier to remove and improving the convenience of use. If the adhesive layer 102 is not completely adhered to the skin, water may enter the drainage channel 15. The absorbent core 16 will play a role, using its efficient water absorption and locking capacity to absorb the water entering the drainage channel 15, thereby maintaining the stability of the dressing and preventing water from further seeping into the area between the medicated dressing component 3 and the covering component 2.
